Dsv41 Flash Offload
Dsv41 Flash Offload is an open source AI model serving tool that runs DeepSeek-V4.1-Flash on a single RTX 3090 GPU and host RAM.
This software serves the DeepSeek-V4.1-Flash model utilizing an EXL3 3.0 bpw quantization on one 24 GB RTX 3090 GPU combined with host DDR4 memory and NVMe storage. It features an OpenAI-compatible API that supports chat with tool calls, reasoning, and completions with a 262,144-token context length. Routed experts are pinned in host RAM, while a staged-DMA prefill engine and a VRAM mirror cache handle fast token generation. An AVX2 CPU expert tier computes cold decode misses directly from host memory, and Engram n-gram tables remain memory-mapped on NVMe. It is designed for developers and researchers who want to run advanced AI workloads locally without needing multi-GPU enterprise clusters.
